BTH_ENUMERATOR_INFO structure (bthddi.h)

  • Article

The BTH_ENUMERATOR_INFO structure contains information about an underlying device and the service that caused the Plug and Play (PnP) manager to load the profile driver.

Syntax

typedef struct _BTH_ENUMERATOR_INFO {
  ENUMERATOR_TYPE   EnumeratorType;
  ENUMERATOR_ACTION Action;
  ULONG             Port;
  ULONG             Flags;
  GUID              Guid;
  ULONG             InstanceId;
  WCHAR             InstanceIdStr[BTH_MAX_SERVICE_NAME_SIZE];
  USHORT            Vid;
  USHORT            Pid;
  USHORT            Mfg;
  USHORT            LocalMfg;
  USHORT            VidType;
  WCHAR             ServiceName[BTH_MAX_SERVICE_NAME_SIZE];
  CHAR              SdpPriLangServiceName[BTH_MAX_SERVICE_NAME_SIZE];

Members

EnumeratorType

Reserved for use by the Bluetooth driver stack. Do not use.

Action

Reserved for use by the Bluetooth driver stack. Do not use.

Port

If the enumeration was caused by a connection request, this member contains the device's port number. Otherwise, this value is undefined. For a L2CAP connection request, the port number also identifies the Protocol/Service Multiplexer (PSM) that is being connected to. For an RFCOMM connection request, this is an RFCOMM data link connection identifier (DLCI).

Flags

A flag that indicates the direction of the request. Possible values include:

  • BTH_ENUMERATORFL_INCOMING
  • BTH_ENUMERATORFL_OUTGOING
  • BTH_ENUMERATORFL_REENUM

Guid

The enumeration protocol or service class GUID. This value is usually obtained from the INF file that loaded the profile driver.

InstanceId

The instance ID of the protocol or service if the BTH_ENUMERATORFL_INCOMING flag is set.

InstanceIdStr[BTH_MAX_SERVICE_NAME_SIZE]

The instance ID of the protocol or service if the BTH_ENUMERATORFL_OUTGOING flag is set.

Vid

The vendor ID of the remote device, which is obtained from SDP.

Pid

The product ID of the remote device, which is obtained from SDP.

Mfg

The manufacturer ID of the remote device, which is obtained from SDP.

LocalMfg

The local radio manufacturer obtained from the HCI.

VidType

The remote device vendor ID type, which is obtained from SDP.

ServiceName[BTH_MAX_SERVICE_NAME_SIZE]

The service name that is used for local services.

SdpPriLangServiceName[BTH_MAX_SERVICE_NAME_SIZE]

The identifier used for remote services.

DeviceString[BTH_MAX_SERVICE_NAME_SIZE]

The device string for the remote device.

Remarks

The IOCTL_INTERNAL_BTHENUM_GET_ENUMINFO call's output buffer contains the information about an underlying device and the service that caused the Plug and Play (PnP) manager to load the profile driver.
